【Abstract】 An experiment was conducted to compare the effect in some bactericides on control of the bacterial fruit spot disease in grafted watermelon seedlings. The number and the percentage of infected and died plants were recorded. The results showed that the most available treatment was with the bactericide Jiashoumi (main component principle element: 2%Kasugamycin) + Wanxing (main component: Flusilazole), with which the infected and died numbers of the plants were 36.4% and 30.4%, respectively; with bactericide Lewubing (main component: 10%sulfate), the infected and died numbers of the plants were 52.9% and 44.8%, respectively; with the treatment of agricultural streptomycin + Yeqingshuang, the infected and died numbers of the plants were 66.1% and 59.7%, respectively; with bactericide Keshade(main component: cuprum oxychloride), the infected and died numbers of the plants were 45.2% and 39.1%, respectively.更多还原
